Teams like the Cleveland Cavaliers or Philadelphia 76ers may get some extra help if they facilitate a deal, but that is completely insignificant compared to how great they will help the Nets become.

One anonymous NBA general manager is really concerned how moves like a Howard to Brooklyn one basically make the league's push for more competitive balance obsolete (via ESPN):

"You can talk about the new (luxury) tax all you want, but if the Lakers get Nash and the Nets get Howard, then what did the new CBA accomplish? You have to realize part of long-term planning is making sure you don't help create teams you can't beat."

His comment gets to the crux of what the league's new collective bargaining agreement was supposed to achieve: give more power to teams in retaining their stars and limit how much control said stars have in deciding where they'll play (i.e. LeBron to Miami, Carmelo Anthony to New York).

The Orlando Magic haveto trade Howard or else they'll get nothing back when he leaves via free agency next season. But why would Cleveland, Philadelphia, or any other team help Brooklyn become a super team?
